An issue was discovered in Denx U-Boot before 2026.04. An integer overflow vulnerability exists in function ext4fs_get_bgdtable, the size calculation can lead to under allocation and this underallocated buffer will be used in memcpy() which could lead to arbitrary code execution, a denial of service, or other unspecified impacts.
